Question type: Maintenance & Repair

went to auto zone, service engine light was on. They told me it was 2-o2
sensors. Replaced them, engine light was still on. Disconnected the battery,
waited 15 minutes, then reattached cables, car started. Stepped on the
brakes and it died. Could not start. took the battery to auto zone, it is good.
Any suggestions.

Try to figure one of two things first 1. Do you have spark 2. Do you have fuel pressure....Find the system giving you trouble first.


Never replace parts based on what someone from a parts store recommends. Getting the trouble codes and doing some diagnostic work is the best way to make accurate repairs. It is possible to get an oxygen sensor code and having an issue with the wiring or other part.
